Question 1

First-degree burns only damage the epidermis.&#8203;

Accepted Answer

First-degree burns only affect the outermost layer of the skin, the epidermis.

Question 2

When external temperatures increase, blood vessels in the dermis dilate to bring more blood flow to the surface of the body.&#8203;

Accepted Answer

This is true. By bringing more blood flow to the surface of the body, heat can be released from the body more easily through sweating and radiation. This helps to regulate the body's internal temperature.

Question 3

The skin receives approximately ____ of all the blood circulating through the body.&#8203;&#10;A) &#8203;one-fifth&#10;B) &#8203;one-third&#10;C) &#8203;one-fourth&#10;D) &#8203;one-half

Accepted Answer

The skin receives approximately one-third of all the blood circulating through the body. This is because the skin is the body's largest organ and has an extensive network of blood vessels, which helps to regulate body temperature and deliver oxygen and nutrients to the skin cells.

Question 4

A burn that involves complete destruction of both the epidermis and the dermis is a ____-degree burn.&#8203;&#10;A) &#8203;fourth&#10;B) &#8203;first&#10;C) &#8203;second&#10;D) &#8203;third

Accepted Answer

A third-degree burn involves complete destruction of both the epidermis and the dermis, making it the correct answer. A fourth-degree burn would involve damage to deeper tissues such as bone or muscle, while a first-degree burn only affects the outermost layer of skin (epidermis) and a second-degree burn involves partial destruction of the dermis.

Question 5

The skin layer that functions as a physical barrier to light and heat waves is the stratum ____.&#8203;&#10;A) &#8203;germinativum&#10;B) &#8203;spinosum&#10;C) &#8203;corneum&#10;D) &#8203;lucidum

Accepted Answer

The stratum corneum is the outermost layer of the epidermis and functions as a physical barrier to outside elements such as light and heat waves. The stratum germinativum, also known as the stratum basale, is the innermost layer of the epidermis responsible for cell division and growth. The stratum spinosum is the layer of the epidermis responsible for producing keratin, which provides strength and water-resistance to the skin. The stratum lucidum is a translucent layer found only in thick skin, such as the palms and soles of feet.

Question 6

&#8203;The regenerative layer of the skin is the stratum ____.&#10;A) &#8203;germinativum&#10;B) &#8203;Corneum&#10;C) &#8203;lucidum&#10;D) &#8203;granulosum

Accepted Answer

The regenerative layer of the skin is the stratum germinativum, also known as the basal layer. It is responsible for producing new skin cells, and is located at the bottom of the epidermis. The other choices include the stratum corneum (outermost layer of dead skin cells), stratum lucidum (only present in thick skin), and stratum granulosum (involved in the production of keratin).

Question 7

&#8203;The stratum ____ is the outermost layer of the skin.&#10;A) &#8203;germinativum&#10;B) &#8203;corneum&#10;C) &#8203;spinosum&#10;D) &#8203;granulosum

Accepted Answer

The outermost layer of the skin is called the stratum corneum, which is composed of flattened, keratinized cells that provide a barrier to the external environment. The other choices (germinativum, spinosum, granulosum) are inner layers of the skin.

Question 8

&#8203;The ____ is divided into the papillary portion and the reticular portion.&#10;A) &#8203;peridermis&#10;B) &#8203;dermis&#10;C) &#8203;hypodermis&#10;D) &#8203;epidermis

Accepted Answer

The dermis is the layer of skin beneath the epidermis, and is divided into two main regions: the papillary portion and the reticular portion.

Question 9

Psoriasis is a common chronic skin disorder that is characterized by red patches covered by thick, dry, and silvery scales.&#8203;

Accepted Answer

Psoriasis is indeed a common chronic skin disorder characterized by red patches covered by thick, dry, and silvery scales.

Accepted Answer

Melanocytes are specialized cells found in the bottom layer (the stratum basale) of the skin's epidermis. These cells are responsible for producing and secreting melanin, the pigment that gives skin its color.
